priformospora indica or piri is an endophytic mycorrhiza in which its growth stimulation effect on host plant by increasing adventitious roots has been reported. the effect of piri on medicinal plant and secondary metabolite accumulation has been less studied. present study was performed in growth chamber conditions (light density 2500 lux, 16 day length and 25 °c) as a completely randomized de...

salicylic acid (sa) and methyl jasmonate (meja) as phytohormone regulate synthesis of secondary metabolites in a wide range of plant species thereby accumulation of phenylalanine ammonia lyase enzyme (pal) and accelerate of oxygen free radicals, protein kinas and no production. the present research designed to evaluate effect of sa and meja elicitation on accumulation of phenolic compounds, fla...

salicylic acid (sa) and methyl jasmonate (meja) as phytohormone regulate synthesis of secondary metabolites in a wide range of plant species by accumulation of phenylalanine ammonia lyase enzyme (pal) and accelerate the production of oxygen free radicals, protein kinase, proline and nitrite oxide content. to study the effect of these compounds on synthesis of secondary metabolites, in two separ...

background: elicitors can trigger defense responses and activate specific genes involved in secondary metabolite biosynthesis. objective: for understanding sa-treatment signaling pathway we determined defense-related compounds and enzymes in s. marianum hairy root cultures. methods: 28 day old hairy roots were treated by salicylic acid (6 mg/50 ml culture) for different times (24, 48, 72, 96 an...

Little is known about how drought stress influences plant secondary metabolite accumulation and how this affects plant defense against different aphids. We therefore cultivated Arabidopsis thaliana (L.) plants under well-watered, drought, and water-logged conditions. Two aphid species were selected for this study: the generalist Myzus persicae (Sulzer) and the crucifer specialist Brevicoryne br...

Woodland sage (Salvia nemorosa) is an important native medicinal plant in Iran and is considered as a rich source of phenolic and flavonoids compounds. The present research was conducted with respect to the optimization of medium for biomass accumulation and secondary metabolite production in cell suspension culture of S. nemorosa. In this research the effects of total nitrogen content (0, 15, ...

imatinib is an orally administered tyrosine kinase inhibitor which inhibits the bcr-abl protein-tyrosine kinase with high selectivity. imatinib is rapidly absorbed from the gut, after oral intake and has an almost absolute bioavailability of 98%. the metabolism of imatinib is mediated by the cytochrome p450 (cyp) isoenzymes in the liver and gut wall. cgp74588 is a major active metabolite of ima...

Cultured plant cells are often highly heterogeneous in terms of secondary metabolite production. We have developed a quantitative determination method that uses an image processing system to estimate such individual cell characteristics as content of the secondary metabolite, anthocyanin. In this study, strawberry cells producing anthocyanins were grown in modified Linsmaier-Skoog medium. Antho...
